Before replaceing the resistor, you better check two things:

If the resistor was a carbon composition resistor then it maybe just
sufficient to replace the resistor. Otherwise check any caps that the
resistor maybe connected to.

The problem with a lot of those old radios that have sat for long
periods are the electrtolytic caps are probably not very good anymore.
Many radios of that vintage used carbon composition resisitors. They
tend to absorb moisture and that causes them to lower their value.
